Propagation effects in high-harmonic generation from dielectric thin films
Shunsuke Yamada, Tomohito Otobe, David Freeman +2
Theoretical investigation is conducted of high-order harmonic generation (HHG) in silicon thin films to elucidate the effect of light propagation in reflected and transmitted waves…
Nonlinear dynamics of electromagnetic field and valley polarization in WSe monolayer
Arqum Hashmi, Shunsuke Yamada, Atsushi Yamada +2
Linear and nonlinear optical response of WSe monolayer is investigated by two-dimensional Maxwell plus time-dependent density functional theory with spin-orbit interaction. B…
High order harmonic generation in semiconductors driven at near- and mid-IR wavelengths
David Freeman, Shunsuke Yamada, Atsushi Yamada +2
We study high order harmonics generation (HHG) in crystalline silicon and diamond subjected to near and mid-infrared laser pulses. We employ time-dependent density functional theor…
Determining the optimum thickness for high harmonic generation from nanoscale thin films: an ab initio computational study
Shunsuke Yamada, Kazuhiro Yabana
We theoretically investigate high harmonic generation (HHG) from silicon thin films with thicknesses from a few atomic layers to a few hundreds of nanometers, to determine the most…
Symmetry properties of attosecond transient absorption spectroscopy in crystalline dielectrics
Shunsuke Yamada, Kazuhiro Yabana
We theoretically investigate a relation between the crystalline symmetry and the transient modulation of optical properties of crystalline dielectrics in pump-probe measurements us…
An efficient method for calculating spatially extended electronic states of large systems with a divide-and-conquer approach
Shunsuke Yamada, Fuyuki Shimojo, Ryosuke Akashi +1
We present an efficient post-processing method for calculating the electronic structure of nanosystems based on the divide-and-conquer approach to density functional theory (DC-DFT…
